Quoted from T7:
The April 2016 update WAS the big update owners were holding their breath for. KISS was pretty much done at that time, but people always want more, and there were still some issues. Now those issues have been addressed also. IMO nobody should continue complaining that KISS was abandoned - it wasn't.
They fixed half or less of the documented bugs. I wouldn't say that's addressing the "issues" that are known. There's still a pretty good list of bugs remaining.
